Spartan-3A/-3AN/-3A DSP - Will CRC scan the SLICE-M if it is configured as a SLICE-L?

Description

In Spartan-3A/-3AN/-3A DSP, the CRC feature scans the loaded bitstream for errors in bitstream and has the option to scan SLICE-L only or SLICE-L and SLICE-M. If a slice M is used as logic (configured as a slice L) will it be checked when scanning only SLICE-Ls?

Solution

No, the tools mask out all SLICE-Ms no matter how they are configured when you scan only the SLICE-L.
